Phase transitions in a single polymer chain: A micro-canonical analysis of Wang-Landau simulations

摘要

We present simulation results for the phase behavior of a single chain for a flexible lattice polymer model using the Wang-Landau sampling idea. Using the micro-canonical density of states obtained with this method we will discuss the ability of an analysis in the micro-canonical ensemble to locate the coil-globule (continuous) and liquid-solid (first-order) transitions found for this problem using a canonical analysis.
